I notice that for many of the LtL rules, especially the ones with large neighborhoods, patterns drawn out of one-cell-thick lines usually die out in the next generation. I think these rules would be easier to explore if an option to make thicker lines with the pen tool existed. Perhaps a script coul...

I already posted this somewhere else, but I'm reposting it because I think it deserves attention. My apologies if this issue is already known: nless the extended RLE [of a bounded-grid pattern] gives the pattern's coordinates, LifeViewer places the pattern in the upper left of the torus but Golly pl...

Beautiful! If you run it it looks like an exponential graph. It's great to have the ones I found hehe It's actually a graph of y = t/x, where t is the generation number. An easy way to tell that it's not an exponential function is to observe that the ratio between the displacement of the nth and (n...

Where does the 61 come from? The transition B7e(south) is encoded by the binary number 101101111, found by reading across the rows of the 3 by 3 grid of cells. This number in decimal is 367, so we need to look at the 367th bit of the MAP rule string. Since each character in this string takes up 6 b...

-- and the range can go up to 50. ...so we can have spaceships that travel at the speed of 50c in Golly? I found a 46C spaceship, but it can't be made into a a 50C spaceship because this design only works for speeds that are one less than primes. #CXRLE Pos=0,0 x = 139, y = 184, rule = R46,C3,M1,S8...

It seems that MAP patterns run upside-down and backwards when run in HashLife instead of QuickLife. Is this a known bug?

This is cool! Having never downloaded Golly 2.9 I don't know how much is really new, but I'm already loving some of the overlay features! Nice job! I'm sure it will take me quite a while to explore all of the features available. I also like how the default file folder is now the main Golly folder, s...

I seem to recall there was once a programming language that used English words in commands as much as it could, and it became widely disliked for being hard to read and also slow to write. I don't know what language it was, though. Maybe COBOL. It's an interesting idea, though. If you want a human l...

Do any still lifes exist from 9 to 19 cells so that every living cell has exactly two living neighbors and if not, then why? I've been searching B3/S2 for years to try to answer this. I'm already pretty sure the answer is "no", because the only available islands seem to be preblocks and rings of ce...

Also, why don't professor and cloverleaf interchange have names yet? :roll: If I cared this much about objects being named on Catagolue, I would have been pestering Calcyman for pages to use "on" instead of "and", to say "trans-block and long hook eating tub" instead of "candlefrobra on trans-block...

I remember last year Kazyan discovered a p87 oscillator here: viewtopic.php?f=2&t=1437&p=27054#p27054

It supposedly broke the record for smallest known P87 oscillator. I don't know whether the previous record holder was a glider loop or not.

I'm kind of surprised that I'm the first I see what you mean. The rational part of my mind knew it had to happen eventually, but I still knew how excited I would be when it happened because I always thought of Bowers as a person whose work was underappreciated. I figured out about Bowers Exploding ...

Congratulations!!! You just made history by making the first post on these forums that mentions Jonathan Bowers!

When I compile it on Ubuntu using gcc ./sfind.c -fopenmp I get this error: /tmp/ccxtPgUA.o: In function `success': sfind.c:(.text+0x15b0): undefined reference to `safeShift' sfind.c:(.text+0x15fc): undefined reference to `safeShift' /tmp/ccxtPgUA.o: In function `doCompactPart2': sfind.c:(.text+0x238...

The prime quadruplet calculator is still available in the LifeWiki pattern collection: http://conwaylife.com/patterns/primequadrupletcalculator.rle Based on the URL the pattern collection was moved to, this link appears to be the natural successor of the links given in the blog post. Before May 2011...

On Golly 2.8, pressing the keys Z, V, T, etc. usually works for undoing, pasting, fitting, etc. However, sometimes it doesn't and Ctrl+Z, Ctrl+V, Ctrl+T need to be pressed instead. This usually happens right after un-minimizing Golly and usually stops as soon as the pattern gets edited.

Google Translate originally did really weird things with lorem Ipsum. They tried to correct it in August 2014 (I think) but not very well, as leaving out the word "lorem" still gives weird results: "ipsum dolor sit amet" becomes "the pain itself is to be loved" (this actually seems to be correct) an...

I've had this problem before. When you choose the "Run Clipboard" option (which is for running scripts) with a pattern in the clipboard, the interpreter thinks it's a Perl script. Instead, you should select "Open Clipboard" which opens the clipboard as a pattern.

Those evolve into the same oscillator, turned 90 degrees. The first is 57 generations ahead of the second.

Another geometry related thought: would the star polygon {4/2} be a compound of two digons, or a square stellated to infinity as in the tetrahemihexacron? Under common usage, {(n*a)/(n*b)} (where n , a , b are integers, and a and b are coprime) is commonly used to represent a compound of n a / b -g...

I read about it in early 2013, I think, in Professor Stewart's Cabinet of Mathematical Curiosities I am so sorry that you had to discover it from a book that: claims that after the T-tetromino stabilizes into a traffic light (which it consistently calls "traffic lights") it cycles between the stage...

Been thinking about geometry lately. Still nice you can create a great dodecahedron from 12 intersecting pentagons, is there such thing as a "great cube"? This would consist of 6 squares, linked together to form a shape like some sort of excavated octahedron (sharing the same vertex and edge arrang...

The only 3-state Generations rule like this is /012345678/3, which Golly can't simulate.

It would be cool if there was a way to start with a pattern (probably confined to an oscillator or still life) and make it out of metapixels by feeding it into a machine. In Life. It's probably impossible to make one that works for all oscillators, though, even if it was supplied with an infinite gr...
